Climate Justice, Life Expectancy, and Gender Disparities in Intermediate Algebra
Tatiana Mihaylova, Bellevue Community College
After an introduction to climate justice and life expectancy, students complete a two-part project. For the first part of the project, students use life expectancy data and plots using the Cartesian coordinate system to make conclusions about the impact of climate change on health and longevity and to explore gender differences. For the second part of the project, students continue to practice math skills, and also practice math communication and build their math literacy, by engaging civically through conversation about the first part of their project, as well as how they can take action to support gender equity through family planning and education for women and girls as a way to address climate change.
